Review Comment:
Unfortunately yes.
The problem is the expectit library can't expect something to not happen.
One potential way to check that nothing is output is to expect `EOF`, and the
`Result` that is returned allows you to get the characters before the match,
which can be checked to be empty. But that `EOF` check needs to be done after
the streams are closed to get an EOF, and with the current API we don't have
the expect object anymore when the streams are closed.
That said, I think maybe an alternative is change this this to a forking
test. That way the stream will close when the subprocess ends and expect should
be able to match the EOF. I'll give that a shot.
